London For my grandmother Roseann Fraser INTROD UCTION Although the First World War ended with the existence of an independent air force in Britain, the majority of the work undertaken in the air during the war had been in aiding the British Expeditionary Force (BEF) to defeat Germany. One of the major developments in air power that came out of the First World War was in its application at the strategic level, through attacks on the German homeland. These attacks had been limited in both scale and damage done but they sowed the seeds for how the Royal Air Force (RAF) would look to develop air power in the future. During the interwar period, army support tasks, such as close air support, battlefi eld air interdiction and artillery spotting and reconnaissance were relatively neglected in comparison to the thinking on how to apply air power at the higher levels of war. At the outbreak of the First World War in 1914, the newly created Royal Flying Corps (RFC) was not held in high regard by the army authorities who were to control its missions. 1 Aircraft, however, were to prove their use in the earliest campaigns of the war when they were initially used in a reconnaissance role. As the accuracy of aircraft reports were verifi ed they were relied upon more and more in this function, and in spotting for artil- lery, 2 so much so that new aircraft designed by the RFC were constructed with army co-operation in mind. 3 They were able to provide ‘invaluable sources of intelligence from as early as 19 August [1914]’ and were able to detect the famous gap between the German First and Second Armies into which the BEF advanced, attacking and halting the German advance. 4 This was confi rmed by further air reconnaissance that ‘revealed that von Kluck’s [the German First Army Commander] change of plan had left vii viii INTRODUCTION his right fl ank exposed, [and] an opportunity presented itself for coun- ter-attack’. 5 This counter-attack manifested itself in the ‘Miracle of the Marne’. Hyde has described the priorities assigned to the RFC as ‘fi rst[ly] reconnaissance and secondly fi ghting’. 6 Air power was employed in both tactical and strategic roles by both the British and the German air forces by the end of confl ict. 7 One of the fi rst major uses of tactical air power during the First World War had been the interdiction operations conducted by the Second and Third Wings RFC on 10 March 1915 at Neuve Chappelle. During this operation, German reserves moving around the Lille–Menin–Courtrai area were bombed as they made their way up to the front lines. 8 The fi rst operational order for the use of close air support for troop movements was at the Battle of Arras in April 1917. 9 Aircraft of the RFC were detailed to attack ‘obstacles in the path of the advancing infantry’. 10 The opening of the third Battle of Ypres saw further refi nement of close air support in the attacks made at Arras. Peter Simkins writes that ‘RFC single-seater squad- rons were detailed to give direct help to the infantry by making low-level attacks on German positions and troop concentrations with machine guns and 25lb Cooper bombs’. 11 As the First World War descended into a mire of trench warfare, the RFC was able to conduct observation and reconnaissance missions over static front lines, giving the relatively inexperienced Corps time and opportunity to improve operational effectiveness. 12 The role the RFC was expected to play also increased as the conditions of static warfare allowed greater accuracy for the spotting of artillery shots. 13 This role in particu- lar was to teach the RFC (and subsequently the RAF) the importance of denying the enemy the freedom to conduct similar reconnaissance and artillery support tasks themselves. This prevented the German air force from discovering troop concentrations prior to an attack and from con- ducting effective reconnaissance for their own offensive actions. 14 In improving successful tactical operations, the RFC developed commu- nication techniques to correct the fall of shot whilst aircraft were still in the air. 15 One of these was the Central Wireless Station, ‘established in late 1916 as part of the efforts to improve the standard air-artillery co-operation. These provided a logical solution to the problem of directing attack aircraft against targets encountered by corps machines’. 16 Observation was of vital importance to higher commands who found themselves out of touch with the tactical situation of battles they were responsible for conducting. ‘The senior RFC offi cer in the fi eld would be expected to have a headquarters INTRODUCTION ix [HQ] close to that of the general headquarters [GHQ]’ in order to provide the Commander-in-Chief (C-in-C) with timely tactical information. 17 Aerial reconnaissance had improved to such an extent that ‘by the end of 1917, photographic reconnaissance was in the need of only small refi nement, mainly in the fi eld of producing more effi cient and effective cameras’. 18 As more tactical air support operations were conducted, more experi- ence was gained and assimilated quickly within the RFC, a remarkable feat when it is remembered that no offi cial thinking or guidelines existed for pilots tasked with ground support operations. 19 Despite this lack of offi cial doctrine, the ground attack role gathered pace during 1916 and when compared to the German air force, the support provided was ‘gen- erally effective, not least in terms of delivery of fi re-power in lieu of artil- lery’. 20 Recent research has noted, however, that despite the lack of any offi cial guidance the RFC’s training manuals did discuss tactical methods and demonstrate the aggressive nature of the Corps. 21 Aircraft from 21 Squadron were used in both interdiction and close air support roles during the opening phase of the Somme offensive in 1916. 22 Jordan has argued that this form of support lacked any real effectiveness, aside from com- parisons against the German air force, until 1917—‘when ground attack missions involved the delivery of bombs in a manner far different from the speculative raids that had been carried out previously’. 23 Further to this, Jordan claims that due to the limited technological development of bombs the Germans found these raids were a ‘source of inconvenience … rather than providing a devastating blow’. 24 Close air support operations, due to their nature of low altitude attacks against ground troops fi ring back, as well as the close co-operation required with friendly ground troops, meant that the results obtained ‘were disappointing when compared with the losses sustained’. 25 This was one of the factors that hampered development of this kind of offensive operation during the interwar years. Even with the formation of the RAF as an independent air force, there was little change in the focus of operations, although there was a public outcry for air attacks to be conducted against German territory after air raids over Britain in 1917. 26 The use of aircraft to attack the British civil- ian population by the German air force shattered the illusion the British public had about the immunity they took for granted. 27 An Independent Force (IF), headed by the future Chief of the Air Staff (CAS), Sir Hugh Trenchard was created to fulfi l this role. At this time, Trenchard was more in favour of aircraft conducting a tactical rather than an indepen- dent strategic role. However, with the end of the First World War and x INTRODUCTION the independence of the RAF at stake, he saw the benefi ts an indepen- dently led and organised air force could bring.
